Mystery frame - lightweight, oversize headtube
I picked this up a while back and just threw some old parts on it that were laying around. Sort of a "borrow me" bike for kids.
It's been repainted (maybe more than once?) but the details on this frame really made me wonder what it is.
It's very light as a frame (didn't weigh but i'd say 3lb, max 4) LARGE downtube, Square chainstays, Wishbone seatstay, Hydraulic guides only, gussetted headtubes, large seat post size and 34.8 seat tube clamp size, serial number on the disc tab, and the kicker is the oversized 1.5 headtube (not tapered).
Sort of seemd like it could be a higher end frame? Or maybe it is just a random offbrand that was made with odd spec?
(It had a Giant seat post clamp but not sure it that's original)
